My invention relates to arche-ryand has vfor its object the provision ofan improved bow for use in this sport.

The bows formerly used in archery were made of wood and the springinessor elasticity of the Ybow varied from time to time with changes in theweather. This made it necessary for the archer to judge and makeallowance for the elasticity of the boweach time he iirst took up hisbow to shoot. There are so many factors, such as elevation, aim,windage, and steadiness in holding the bow and discharging the arrowtherefrom, which must be taken into account in archery that it is ofgreat importance to the improvement of this sport that changes in theelasticity of the bows used be eliminated if possible.

It is, therefore, an object of my invention to provide a bow, theelasticity of which remains practically constant through all normalconditions of use.

The wooden bows formerly in common use are very expensive to make, anddeteriorate comparatively rapidly.

It is a further object of my invention to provide a bow which will berelatively inelipensive to make and which will have a practicallyunlimited life.

Further objects and advantages will be made manifest in the followingdescription and in the accompanying drawings which illustrate apreferred embodiment of my 1nvention. In the drawings,

Fig. 1 is a full length side elevational view of one form of myinvention.

Fig. 2 is a full length side elevationalview of another form of myinvention.

Figs. 3, 4, 5, and 6 are horizontal sectional views taken on thecorrespondingly numbered lines of Fig. 1.

Figs.' 7, 8, 9, and 10 are horizontal sectional views taken oncorrespondingly numbere lines of Fig. 2.

Fig. 11 is an enlarged vertical sectional view of the medial portion ofthe bow member of the bow, shown in Fig. 1.

Fig. 12 is an enlarged vertical sectional view of the medial portion ofthe bow members of the bow, shown in Fig. 2.

Referring specifically to the drawings, 15

indicates a bow constituting one form of my invention, which has a bowmember 16 formed of a pair of metal tubes 17, each of which ispreferably tapered from the inner end toward the outer end thereof. Eachof the tubes 17 has a string hook 18 provided on its outer end. The twotubes 17 are placed with their inner ends abutting against each other sothat opposite end portions of a connector bushing 20 extend into theadjacent ends of the tubes 17. Separation of the tubes 17 and thebushing is prevented by any suitable means, such as solder run inbetween the bushing 20 and these tubes. Formed of any suitable material,such as rubber, cork, or the like, about the medial portion of the bowmember 16 is a handle 21. The outer ends of the tubes 17 are bent auniform distance in the same direction from the axis of the centralportion of the body member 16. As clearly shown in Figs. 3 to 6inclusive, the tubes 17 are oval in cross-section so as to give the bowmember 16 a maximum springiness or elasticity. Caught over the'hooks18are loops 25, formed on the opposite ends of a bow string 26, so thatthe bow member 16 is bent under a slight tension.

Referring now to Fig. 2, 30 indicates another form of the bow of myinvention which has a pair of bow members 31 and 32, each of whichisconstructed in substantially the same manner as the bow member 16 ofthe bow 15 except that each pair of corresponding ends of the bowmembers 31 and 32 is connected together by one of a pair of hooks 34.Formed medially about the bow mem-- bers 31 and 32 so as to hold thesein spaced relation is a handle 35 which may be formed from any suitablematerial such as rubber or cork. f

Caught over the hooks 34am-loops formed on the opposite ends of a bowstring 36 which is of such lengthas to draw the hooks 34 'tgward eachother and maintain the bow members 31 and 32 under constant compress1on.

As clearly shown in Figs. 7 to 10 inclusive, the tubular bow members 31and 32 are oval in cross-section. Whilelthis construction is notessentialto the proper operation of the bow 30, it is highly desirableas the tubes of oval cross-section have a maximum elasticity.

While I have illustrated but two forms of my invention, it is to beunderstood that one skilled in the art might make numerous changes inthe actual structure illustrated without departing from the spirit ofthe invention or the scope of the appended claims.

I claim as my invention:

l. In an archers bow, the combination of: a bow member including a pairof tubes disposed end to end and connected by a tubular bushingextending into adjacent ends of said tubes; a handle surrounding theconnected ends of said tubes; and a string joining outer ends of saidtubes.

2. In an archers bow, the combination of: a plurality of bow members,each including a pair of tubes disposed end to end and connected by atubular bushing extending into adjacent ends of said tubes; a handlesurrounding tlie connected ends of said tubes; means for connectingpairs of corresponding ends of said bow members; and a string extendingfrom one of said pairs to the other of said pairs.

3. In an archers bow, the combination of: a bow member tapering towardits extremities and including a pair of tubes disposed end to end andconnected by a tubular bushing extending into adjacent ends of saidtubes; a handle surrounding the connected ends of said tubes; and astring joining outer ends of said tubes.

4. In an archers bow, the combination of: plurality of bow members, eachtapering -r-ward its extremities and including a pair of tubes disposedend to end and connected by a tubular bushing extending into adjacentends of said tubes; a handle surrounding the connected ends of saidtubes; means for connecting pairs of corresponding ends of said bowmembers; and a string extending from one of said pairs to the other 0fsaid airs.

5. combination as in claim 1 in which said bow member is oval incross-section.

6. A combination as in claim 2 in which said bow members are oval incross-section.

7. In an archers bow, the combination of: a bow member including a pairof metallic tubes disposed end to end and connected by a. tubularbushing extending into adjacent ends of said tubes; a handle surroundingthe connected ends of said tubes; and a string joining outer ends ofsaid tubes.

8. A combination as defined in claim 7 in which said metallic tubes areoval in crosssection, and become smaller in outer dimenieons near theextremities of said bow mem- 9. In an archers bow, a handle portion,

a pair of spaced, tubular metal limbs exi tending from each end of saidhandle portion, and a tip connecting the outer ends of each pair oflimbs.

10. In an archers bow, the combination of: a plurality of bow members,each including a pair of tubes disposed end to end and connected by atubular bushing extending into adjacent ends of said tubes; a handlesurrounding the connected ends of said tubes; means for connecting pairsof corresponding ends of said bow members; and a string extending fromone of said pairs to vthe other of said pairs.
